FASTENING DEVICE.

Specification of Letters Patent.

Patented Apr. 5, 1921.

Application filed March 3, 1920. Seria1'No. 363,075.

T 0 all whom it may concern:

Be it known that I, CHAnLEs VVns'r, a subject of the King of GreatBritain and Ireland, residing at London, England, have invented certainnewand useful Improvements in Fastening Devices; and I do hereby declarethe following to be a full, clear, and exact description of theinvention, suchas will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to fastening devices for dresses, clothes and thelike and refers to that class of fastening formed in two parts, one parthaving a raised tongue or bridge adapted to engage between'the turned upedges of the other part.

In fastening devices of this type it has been proposed to form onemember with downwardly and outwardly inclined edges, r p

be clearly understood 1 W111 now proceed to describe the same withreference to the drawso as to engage the upwardly and inwardly turnedinclined edges of the other part, the j one part having a point or studwhich, when the two parts are in engagement enters a hole in the otherpart. It has also been proposed to bend the outer opposite edges of onepart inwardly and to attach to the 7 other part two outwardly andoppositely extending tongues adapted to engage beneath the inwardlyturned edges of the other part, the two parts being retained inengagement by astop. In other forms the one part has attached thereto astud or button with an enlarged head adapted to engage a keyhole slot orrecess in the other part.

According to the present invention the two members of the device arepreferably formed by stamping. One of the members is formed or providedplate, leaving the tongue between them.

The other half of the fastener is provided with a member constituted bya tongue or by a bridge or the like which is formed narrow at one end orwith an enlarged central portion said bridge projecting somewhat abovethe general level of the plate,

with a. centrally disposed slightly projecting bridge or tongue 'tiallyof the shape of a U The relative dimensions of the two parts i of thefastener are such that the member provided with the tongue, bridge or'the like can he slid with respect to the other part, so that it entersat the one end of the receptive portion and, as it is drawn along thesame, the edges of the bridge come under the inwardly projecting edgesforming the outline of the receptive portion, thus constituting a securefastener.

'I prefer to provide additional'means for holding the parts lockedtogether after they have been engaged. This means may'consist of aprojection, or projections on the bridge adapted to engage in a recessor recesseson the tongue, of the receptive portion.

Or again the projections may be onthe I may be in the bridge.

And in order that my said invention may ing accompanying thisspecification, which shows by way of example and to a greatly enlargedscale a number of formsof fasteners made accordingto my invention.

Referring to Figures 1 to 5, in which Fig.- l

1 and Fig. 2 show respectively a plan and section of one member of thefastener,-Figs. 3,4, and 5 are a planand two sections at right angles toone another of the other member of the fastener while Fig. 4 is aVertical section of a modified form of the member shown in Figs. 3 to 5.The member shown at Figs. 1 and 2 consists of a plate'a which ispreferably provided with perforations a to enable it to r be sewn to thematerial. This plate a is formed or stamped with a bridge 5, having acentral perforation or recess 0. I

The other half of the fastener consists of a plate (2 stamped up on eachside substanat g 9 but the U is broken at the bottom. The tongue It mayeither be formedas shown'in Fig. 46 or it may in Fig. P, the U piece iscontinued around and not broken, as shown in this figure the lower endsof the turned up portions 9 being joined together.

' With this construction it is simply neces-V be continued as shown atFigs. 3 and 4;, 7 so that it forms a bridge rejoining the sary to slidethe enlarged portion 6 of the bridge 6 downward under the turned overedges 5 of the U shaped piece 9' until the springy portion f of thetongue or bridge it engages the hole 0.

Figs. 6 to .10 are similar views to Figs. 1 to 5 of another form offastening.

In this case one of the members, namely that illustrated at Figs. 6 and7 is provided with a bent up bridge 5 furnished with a perforation orrecess 0.

The other member illustrated at Figs. 8 to 10 is provided with twoparallel stamped out and turned over portions 76 70 as will be seenclearly from the drawing and m is an embossed head located between thestamped portions 70. I

On the outer sides of the stamped up portions 7c is, the metal is formedwith a projecting rib k k to give additional strength.

With this construction it is simply necessary to slide the bridgebetween the turned in portions is of the other part of the fasteninguntil the hole or recess 0 engages over the head m. The bridge I) owingto its formation cannot slide entirely through between the bent upportions is 70. v

Figs. 11 to 14: show further modifications. In this case the plate a isprovided with a tongue p carrying a central diskor button The other partof the fastening is formed with a tongue 9 of U shape, the outer edgesof the U being bent over at 7.

With this form of fastener the raised edges of the Ushaped portion arestepped up on the inside, as seen clearly at Fig. 14.

This stepped up portion forms a recess or pocket into which the disk orbutton 19 is drawn when the members of thefastener are completelyengaged and the construction acts in a similar manner to the head,engaging with a recess in the other form of the fastener to prevent selfdis-engagement.

In some cases where the members are stamped out from plates the bridgeand receptive portion therefor may be stamped up without cutting throughthe metal of the plate. 7

It will be understood that the particular method of constructing themembers of the device may be varied without departing from the principleof my invention.

Devices of the foregoing description possess the great advantage ascompared with those at present in use, that they can be passed throughwashing and-like machinery without becoming damaged, as the parts are sostamped, that the pressure, such as that produced by passing themthrough wringing rollers will not bend them out of shape.

What Iclaim as my invention and desire to secure by Letters Patent ofthe United States of America is '1. A fastening device of. the typedescribed consisting of two members each jecting spaced apart to receivethe end of the bridge formed from a single piece of material, one ofsaid members constituting a bridge portion comprising a plate havingraised centrally thereon a bridge, said bridge extending above thegeneral level of the plate,

and formed of restricted width at at least one end and a second memberconstituting a receptive portion comprising a plate having raisedthereon two upwardly and inwardly projecting sides spaced apart to receive the bridge of the other member the disengage- 2. A fasteningdevice of the type dey scribed comprising a bridge portion and areceptive portion each formed of a single piece of material, the bridgeportion comprising a plate having raised centrally thereon a bridgeextending above the general level ofthe plate and joined thereto at eachend, the width of which at, at. least one end is restricted, wh le thereceptive portion comprises a plate, having raisedf thereon two upwardlyand inwardly prosides, the inner edges of which are of restricted width,the material between the upwardly projecting sides constituting a tonguehaving a central recess formed thereon to engage a central head, on thebridge of the bridge portion, for the purposes set forth. t

3. A fastening device of the type described receptive portion eachformed of a single piece of material, the bridge portion comprising aplate having raised centrally thereon a bridge extending. above thegenerallevel of the plate and'joined at each end. thereto, the width ofthe bridge being restricted at at least one end, while the receptiveportion comprises a plate having raised thereon two upwardly andinwardlyextending sides, spaced apart to receive either end of the bridge formedon the bridge portion, the material between the sides of the receptiveportion constituting a tongue and formed witha recess with which engagesa head on the bridge of the bridge portionwhen the two members are inengagement for the purposes set forth.

4. A fastening device of the type described comprising a bridge portionand a com risin a brid e ortion and a ceptive portion comprises a platehaving raised thereon, so as to extend above the general level of theplate, two upwardly and inwardly projecting sides, open at each end, theupwardly projecting sides of the receptive portion being spaced apart toretain the wide portion of the bridge of thebridge portion, for thepurposes set forth.

5. A fastening device of the type described, comprising a bridge portionand a receptive portion each formed from a single piece of material,said bridge portion comprising a plate having raised centrally thereon abridge, said bridge being of restricted width at at least one end,extending above the general level of the plate and parallel with theupper surface thereof and being joined to said plate at at least oneend, while the receptive portion comprises a plate having raised thereontwo receptive upwardly and inwardly projecting sides, the

inwardly projecting sides being above the general level of the plate andtheir inner facing edges being spaced apart to permit of the passage ofthe end of the bridge of restricted width, the material of the platebetween the sides of the receptive portion constituting a tongue havinga recess with which engages abead on the bridge when the'two members areengaged, for the purposes set forth.

In witness whereof I affix my signature.
